Vibrators are the oldest sex toys. They have been around since the Victorian era, when they were called "massagers."

There are many types of vibrators: some are designed to be inserted into the vagina, while others fit over the clitoris and provide stimulation through vibration. There are also vibrating bullets that can be used during oral sex.

Vibrators come in a range of sizes and styles, from small, handheld devices to large wand-style vibrators. Some vibrators are designed to be used by women during masturbation; others are designed for couples' use during intercourse or foreplay (or both).

Vibrators can be used on their own or in conjunction with other forms of stimulation (such as oral sex or manual stimulation). They can also enhance the sensations from other forms of stimulation by providing additional stimulation—either through vibration or an increase in friction—to areas where there is little sensation otherwise.
